Excerpt from Some Contributions From the Laboratory of Physics of the University of Illinois, Urbana, Illinois, 1912-1914 As the pressure is reduced the positive column recedes towards the anode. The Spark is now passing with more difficulty as may be shown by the parallel Spark gap. We now notice a new phenomenon within our discharge tube. The tube is beginning to glow with a faint greenish phosphores cent light which is rapidly becoming more and more marked. The color of this light depends on the kind of glass used - soda glass producing a greenish and lead glass a bluish phosphores cence. This phosphorescence is due to minute particles shot off normally from the surface of the cathode and impinging on the surface of the glass. These particles travel in straight lines and have a high velocity. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
